Abstract
A storage battery is provided in which an expand grid is improved with respect to the widths of grid wires, the sectional areas of nodes, and the shapes of meshes, whereby the productivity of the expand grid can be enhanced and the life performance can be improved. As means for attaining the object, a storage battery in which an expand grid is used as a battery plate, the expand grid being a grid member which is formed by expanding a side portion of a collector frame portionof a metal sheetto connect a large number of grid wiresto one another in a net-like shape, is configured so that widths of grid wiresof a row which is directly connected to the collector frame portionof the expand grid, and a lateral end row are larger than widths of grid wiresof at least one of intermediate rows.
